Steps to Replace Your Dewalt Circular Saw Blade 18V
Replacing your Dewalt circular saw blade may seem intimidating at first, but by following these steps, you can do it efficiently and safely.
1. Power Down and Prepare
Before attempting to replace the blade, make sure to disconnect the power from your saw. Remove the battery from your 18V Dewalt circular saw to ensure that it cannot suddenly turn on while you’re working. Safety should always be your first concern.
2. Identify the Blade Lock Mechanism
Most Dewalt circular saw models come with a blade lock feature that holds the blade in place while you work. Locate this mechanism:
– It will typically be a button located near the blade housing or on the saw’s base.
– Press the button down to lock the blade in place, making it easier to unscrew the bolt that holds the blade.
3. Remove the Blade Bolt
Using the appropriate wrench, loosen the bolt that secures the blade to the saw. Here’s how:
– Turn the bolt counterclockwise. It may require some force if it hasn’t been removed in a while.
– Once it’s loose, you can finish unscrewing it by hand.
4. Take Off the Old Blade
Once the bolt is removed, carefully slide the old blade off the spindle. Be cautious as the edges of the blade are sharp.
5. Install the New Blade
Now it’s time to fit the new blade onto the saw:
– Observe the direction of the teeth on the old blade. The new blade should be installed in the same orientation—this ensures that the blade cuts correctly.
– Slide the new blade onto the spindle, aligning it with the shaft properly.
6. Reattach the Blade Bolt
With the new blade in position, it’s time to reattach the blade bolt:
– Place the bolt back onto the spindle and hand-tighten it, ensuring it goes in smoothly.
– Once it’s snug, use the wrench to tighten it securely.
7. Release the Blade Lock
Now, release the blade lock mechanism. This will allow the blade to spin freely when powered on.
8. Reattach the Battery
With the replacement successfully completed, reinsert the battery into your circular saw.
9. Test the Tool
To ensure everything is functioning correctly before starting a project:
– Stand clear of the blade and make sure your hands and equipment are away from the cutting area.
– Power on the saw and let it run for a brief moment. Check for any unusual sounds or vibrations and ensure it operates smoothly.
